4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mike Marciniszyn <mike.marciniszyn@xxxxxxxxx>
commit eefa1d8961584c5b76afded94960ca4344bc638b upstream.
The __must_hold() is sufficent to correct the sparse
context imbalance inside a function.
Per Documentation/sparse.txt:
__must_hold - The specified lock is held on function entry and exit.
Fixes: Commit c0a67f6ba356 ("IB/rdmavt: Annotate rvt_reset_qp()")
